不同黄瓜品种在种子萌发期对NaCl盐胁迫的响应

Abstract

用150 mmol/L NaCl盐溶液对10个不同黄瓜品种进行芽期胁迫处理,调查9个生理指标的变化，采用隶属函数法综合评价不同品种黄瓜的耐盐能力。结果表明:不同黄瓜品种的不同生理指标对NaCl盐胁迫的响应不同。采用隶属函数法，综合评价10个不同黄瓜品种的耐盐能力依次为秀丽旱黄瓜 > 津耘黄瓜 > 玉宝、本地黄黄瓜 > 春宝王中王 > 本地王黄瓜、春秋旱黄瓜 > 绿翡翠 > 如玉 > 韩研银丰黄瓜。 10 cucumber varieties were treated with 150 mmol/L NaCl salt solution at seed germination stage, and 9 physiological indexes were investigated. The salt tolerance ability of different cucumber va-rieties was evaluated by membership function method. The results showed that different physio-logical indexes of different cucumber varieties had different responses to NaCl salt stress. The salt tolerance ability of 10 different cucumber varieties was evaluated as follows: xiulihan > Jinyun > Yubao, local yellow > spring Baowangzhongwang > local king, chunqiuhan > lvfeicui > Ruyu > hnayan Yinfeng.
